MACHINE FOR PLOTfllNG SOAP, etc.

SPECIY'ICAI'ION forming part of Letters Patent No. 296,878, datecl April15, 1884-.-

Application filed July 23,1883. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS S. RUTSCHMAN, a citizen of the UnitedStates, residing in the city and conntyof Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in Machines forPlotting Soap, &c.,

which improvement is fully set forth in the following specificationandaccompanying drawings, in which- Figure 1 is a top or plan view of amachine for plotting soap, 8rd, embodying my invention, part of thecasing thereof being removed. Fig. 2 is an end view thereof. Fig. 3 isavertical section in line x a, Fig. 1. Figs. 4 and 5 are views ofdifferent forms of dies that may be employed.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a machine for plotting soap,formed of a casinghaving two spiral conveyers arranged parallel within a casing, onopposite sides thereof, constructed of two bodies communicating witheach other at their place of junction, whereby the soap is dischargedproperly plotted and in such condition that it retains its shape, andmay be sliced or otherwise manipulated without lia-' bility to break orcrumble.

Referring to thedrawings, A represents a casing formed of twopartlycylindrical-shaped bodies, 0, arranged parallel and communicatingon their inner sides or place of junction. NVit-hin the casing twocylinders, B, are mounted, the same being placed side by side and havingtheir peripheries spirally grooved, the groove of one cylinder extendingin reverse direction to that of the other cylinder, the two cylindersbeing geared together and re: ceiving power in any suitable manner,their direction of rotation. being toward each other. The casing A has ahopper or inlet, 0, and a dischargespont, D, the latter being, at orabout the middle of the proper end of said casing, moved around bothconveye'rs, and also between the same, and in said spout is a die,E,-which is held in place by aunioncoupling or nut, b. The opening ofthe die may be of any suitable contour, the latter being imparted to thesoap as it leaves the spout, two forms of dies being shown in Figs. 4and 5.

The operation is as follows: A mass of soap is fed into the casingthrough the hopper or inlet 0, and carried along by the two spiralcylinders and conveyed through the casing to the discharge end of thesame, where the streamsof soap unite, forming a single stream, whichenters the spout D, and is forced through the die E, thus having thecontour of the latter imparted to it. The soap, as shaped or plotted, isdirected on a table or other support, where it may be sliced orotherwise manipulated according to requirements. It will be seen thatthe mass while within the casing is so thoroughly worked, intermingled,and incorporated by the two conveyers that it is discharged in ahomogeneous condition, whereby the material after leaving the dieretains its shape, and may be sliced or otherwise manipin lated withoutliability to break or crumble.

By unscrewing the nut b the die E may be removed and replaced by one ofdifferent contour,.which latter being applied will be held by the nutagain fitted to the dischargespout and clamping the die thereto.

It is evident that by themeans-hereinbefore stated, candy, glue, andother plastic substances may be plotted, it being necessary to employ adie adapted to impart-the proper shape to said substances.

A single screw has been used in machines for plotting soap; but theoperation of the same is such that the soap receives a twisted shape andglazed surface as it leaves the screw, thus necessitating a perforatedplate or breakerto overcome the injurious effects of the same, thisbeing obviated by my construction; and

I therefore disclaim the use of a single screw.

I am also aware of the use of two cylinders distinct from each other,communicating with different spiral convey ers, and likewise disclaimthe same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a machine for plotting soap, 810., two spiral conveyors arrangedside by side, in combination with a casing formed of a two-part body,the two conveyers being located in the opposite sides of said casing,substantially as and for the purpose set forth.
